Hi,i already search for this problem, and found that obfuscation of the jar file should work, but it does not work in my case.
It is a very simple app(MIDP-1.0), with just a few sprite operations e no external libs (i'm just importing the default J2ME classes javax.microedition.*). The game is just about two classes boxApp.class and mApp.class
Does anyone can help me? I think this is probably a simple thing, but i'm trying hard all night and don't a have a clue
Thanks in advance

You should un-jar (or unzip) your jar file and see if you have java.* or javax.* packages in it. If you do, the obfuscating did not work. You need to either re-config your obfuscator or just re-name those packages in your source code.

I'm having the same problem on a Nokia series 40 phone. I've checked my jar and there's nothing there that looks out of place as you suggest. Any other ideas???
